UNLV study shows frog embryos can fully regrow their eyes after injury, debunking a belief that they can’t.
Undergraduate Honors College student Sophia Quinton has overcome personal adversity to win prestigious Barry M. Goldwater Scholarship.
Life Sciences In The News
A UNLV scientist and her team have found that frog embryos can fully regrow their eyes after injuries, a breakthrough that may lead one day to the ability to orchestrate tissue regeneration in humans.
Diamonds, the super-strong and brilliant crystals of carbon atoms produced under the Earth’s crushing pressures, are typically valued for their beauty and durability. But scientists also value them for another reason: They contain all kinds of hidden messages about the Earth’s mantle. You just need the right tools to read them.
A new report published today in Science suggests that pockets of liquid water may exist up to 500 miles beneath Earth’s surface—far deeper that previous estimates. This conclusion was reached after scientists discovered a rare form of crystalized water known as ice VII in diamond samples recovered in Africa and China. These ice VII samples are the first time this form of crystalized water has been seen in nature and led the International Mineralogical Association to declare ice VII as a new type of mineral.
X-ray spectroscopy helped to investigate the diamond crystals collected on the fields in Africa, China, Zaire and Sierra Leone, and to find in them microinclusions ordinary water ice, but in a rare cubic phase of ice VII. The find, which scientists report in an article published by the journal Science, may lead to a reassessment of our ideas about the amount of water hidden in the bowels of the Earth.
Trapped in the rigid structure of diamonds formed deep in the Earth’s crust, scientists have discovered a form of water ice that was not previously known to occur naturally on our planet.
